Hello,

I finally had time to return to this issue. To avoid the confusion caused by old
kernels, I reproduced the problem on openSUSE Factory (kernel 2.6.38 and
autofs 5.0.5 with all kernel.org patches applied). Here's the
configuration used:

# cat /etc/auto.master
/data	/etc/auto.data

# cat /etc/auto.data
isos	-fstype=nfs,ro,rsize=8192,wsize=8192,intr,nolock,nosuid libre:/isos

# cat /etc/sysconfig/autofs | grep -v '^#'
AUTOFS_OPTIONS=""
LOCAL_OPTIONS=""
APPEND_OPTIONS="yes"
USE_MISC_DEVICE="yes"
DEFAULT_MASTER_MAP_NAME="auto.master"
DEFAULT_TIMEOUT=600
DEFAULT_BROWSE_MODE="yes"
DEFAULT_LOGGING="debug"
DEFAULT_MAP_OBJECT_CLASS="nisMap"
DEFAULT_ENTRY_OBJECT_CLASS="nisObject"
DEFAULT_MAP_ATTRIBUTE="nisMapName"
DEFAULT_ENTRY_ATTRIBUTE="cn"
DEFAULT_VALUE_ATTRIBUTE="nisMapEntry"
DEFAULT_AUTH_CONF_FILE="etc/autofs_ldap_auth.conf"
MAP_HASH_TABLE_SIZE=1024

I'm attaching the automount debug logs showing the following sequence:

- automount startup
- mount of an NFS volume (/data/isos)
- failed attempt to trigger the expiration of the mounted volume (sending
  SIGUSR1)
- successful attempt to trigger the expiration of the mounted volume
  (sending SIGUSR1 again)

I also confirmed that the problem no longer happens if I revert the
following commit:

commit 08aafab4c1d0ab6227c80f8cd1086ae78556a370
Author: Ian Kent <raven@themaw.net>
Date:   Thu Sep 9 11:10:47 2010 +0800

    autofs-5.0.5 - fix direct map not updating on reread

Philip, do you think you could try to revert it in your setup/package just
to confirm this "works"?

Thanks,
Leonardo
